Abstract:
Pure cultures of chicken gut microbial species may be important and necessary in explaining the function of the gut microbiota and also contribute to the development of potential new probiotics and bioactive metabolites of the gut microbiota. The main objective of this study is to isolate yeasts from chicken samples collected in the regions (Sebseb, Metlili, Mansoura, Ben Isguen) located in Ghardaia, and then to study their biotechnological effectiveness. Analysis of the fungal microflora of chicken feces from our samples showed that it contained on average 13 yeast strains. The initial identification of isolates of this particular microflora was based on macroscopic and microscopic study. It did not show antibacterial activity against Salmonella spp. Escherichia coli (E52), Bacillus subtilis (ATCC6633), Listeria monocytogenes. We further characterized the probiotic properties, the latter was not hemolytic, is an antioxidant and auto-aggregating.
